cloudflare 跳错 cf cdn报 429 Too Many Requests,Retry-After间隔 如何关闭禁用HTTP DDoS防火墙触发拦截?例子
HTTP request sent, awaiting response... 429 Too Many Requests
2020-10-15 19:03:39 ERROR 429: Too Many Requests.
解决方法未知,不知道如何解决
通过wget测试,19:12:07-19:13:08,发现间隔为1分钟,每1分钟只能wget一次,第二次就会跳出429的错误
此时使用--header绑定源站服务器进行访问,尝试测试请求源站服务器10次,都没有任何异常情况发生。
cloudflare 错误完整响应如下
HTTP request sent, awaiting response...

观察后台,可以看到触发了HTTP DDoS防火墙,可能和这个有关
通过检索服务器IP,果然发现了相关的HTTP DDoS触发拦截
HTTP DDoS防火墙介绍:https://www.cloudflare.com/zh-cn/learning/ddos/http-flood-ddos-attack/
我怀疑和这有关,网站请求全部跳这错误,这是误杀啊!渣渣CF,限制10个都好啊,,居然1分钟只能访问1次!

实锤了,就是CF的锅,正好有Retry-After: 59 的响应头,刚好是1分钟
折腾了半天,,发现这破玩意,,还关不掉
连接关闭,允许,阻止一气呵成
cloudflare cf cdn何时会启用HTTP DDoS防火墙触发拦截?我是否能关闭它?
